OK, I have a problem. My otherwise pristine pond water had developed
suspended algae - large stuff. It *will* clump, but most of it's being
removed by my pre-filter. I just posted shots of it on my "website" below.
There are microscopy shots of it at 40, 100 and 400X. If you have any ideas,
please let me know!
